Concurrent Calibration
Concurrent Sprint LCs have up to four test ports and have one pressure
transducer for each channel (or test port). Concurrent testers are not
available with flow sensors. The pressure calibration menu looks similar
but displays a reading for all sensors at the same time. In a multiple-
channel concurrent tester, the sensors will be listed from Sensor 1 to
Sensor 4 depending on the number of sensors installed.
Concurrent Calibration Ports
Any of the test ports may be used for calibration as long as the remaining
test ports are capped and leak tight. Air is sent out of the Sprint LC to
supply a calibrated standard for comparison to the Sprint LC, same as in a
single channel Sprint LC. The difference here is all ports will be supplied
with air pressure.
Setting Concurrent Calibration Points
The concurrent calibration menu allows all pressure sensors to be
calibrated at the same time. Each transducer does have an individual
reading as shown below. However, when the zero point for one is set it is
the zero setting for all. The same is true for the rest of the calibration
points. For example, when 10 psig is stored, values are stored for each
sensor, Sensor 1 to Sensor 4, depending on the number of sensors
installed.
